I've messed with it so much now, it's hard to tell what the original
problem was.  This now works according to the watch window, watching
debug.

==============================start code=========================
// PIC UART Baud Rate
#define ProcessorClock 20               // Processor clock speed in MHz
#define BitRate 19200           // bits per second
int debug;                      // Something to watch as we debug


void main(){
  debug=ProcessorClock;
  debug=BitRate;

===============================end code ============================

     Kelly Kohls pointed out that there should not be a semicolon after
the defines. Checking my C reference, I see that's correct. There should
be no semicolon at the end of a define. I'm just so used to seeing
"missing semicolon" errors whenever I write in C or Pascal, that I guess
I'm a bit too liberal with them.
        It's interesting that the "step by step" calculation below works, but if
I try to calculate brg in one expression, it messes up.

void InitSerial(){
// Initialize on chip UART.
  long brg;                     // Calculate baud rate generator divider step by step
  brg=62500;
  brg=brg*ProcessorClock;
  brg=brg/BitRate;
  brg=brg-1;

OpenUSART(USART_TX_INT_OFF&USART_RX_INT_OFF&USART_ASYNCH_MODE&USART_EIGHT
_BIT&USART_CONT_RX&USART_BRGH_HIGH,brg);
}

Thanks for the help, all!
